METALLIC POLE FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 397,767, dated February 12, 1889.

Application filed November 22, 1888. Serial No. 291,551. (No model.)

To aZZ whom it may concern:

Be it known that I, FRANCIS H. \VELLS, of Racine, in the county of Racine, and in the State of Wisconsin, have invented certain new and useful Improvements in Metallic Poles for Vehicles, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof.

The invention relates to metallic poles designed for use with wagons, omnibuses, harvesters, and other vehicles and machines of heavy draft, or such as require a pole combiningstrength with lightness; and it consists in certain peculiarities of constructiomas will be fully set forth hereinafter, and pointed out in the claim.

In the drawings, Figure l. is a bottom plan view of my improved pole. Fig. 2 is an end view, partly broken away at one point. Fig. 3 is a view corresponding to Fig. 1 of part of the device on an enlarged scale and partly broken away to show the construction. Fig. 4 is a view similar to 2, showing a modified construction.

My device is rolled out of suitable metalsuch as wrought-iron, steel, or malleable iron being originally a flat sheet of metal with the strengthening ribs or projections a Z) a extending from side to side, the said sheet tapering, so that when it has been formed into the shape shown in Fig. 1 the left-hand end will be about double the size of the right-hand end, with an even taper from one end to the other. The sheet, with its ribs, is bent over a suit-able former; but the method of making the pole forms no part of my present inven-.

t-ion, and is only described for the sake of clearness.

One edge of the described sheet is turned over so as to form a rib, d, which, when the pole is complete, will be opposite the rib b, as shown in Fig. 2, and that part of the sheet adjacent to said turned-up end is preferably shouldered or offsetted, (of course before said edge is turned up to form the rib 01,) as at 0, so that when the other edge of the sheet is brought to place, as shown at e, the joined edges may be flush on the outside, and the overlapping parts are then united by suitable bolts or rivets, ff.

If preferred, the offset 0 may be dispensed with, and then the edge marked 6 would merely overlap the end having the inturned edge (Z, and be united by rivets f, as before; but the construction first described and illustrated presents a neater appearance.

In Fig. 4. I show a modified construction, wherein my improved pole is made of two parts rolled out from two sheets,.but other wise the same, the diiference being that each sheet would be rolled with only one rib a and each sheet would have an int-urned edge 6!, (turned from the previously offsetted part c, if preferred, as shown,) and one of these inturned edges d would then take the place of the rib b in the form shown in Fig. 2, the two sheets, after being formed into proper shape, being united by bolts or rivets f f on top as well as below.

I have not deemed it necessary to show any especial means of uniting my pole to the Vehicle or machine to which it is to be attached, as such means would necessarily diit'er with each different kind of vehicle or machine, and because it is well understood how poles are commonly attached, as by passing between hounds and being bolted thereto, or any equivalent means.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A tubular vehicle-pole formed of one or more pieces of metal having longitudinal strengthening-ribs rolled therefrom and projecting inwardly the entire length of said pole, the edges of said metal pieces overlapping and being united by bolts or rivets.

In testimony that I claim the foregoing I have hereunto set my hand, at Racine, in the county of Racine and State of Visconsin, in the presence of two witnesses.

FRANCIS H. IVELLS.
